Same here, on AM from Montreal last summer.
Even if we have been told In Montreal that with a 5+ hours stop we will have to get our luggages and checked them in again.
When we arrived in Mexico airport, they never showed up on the carroussel and were transfered directly to our flight to ZIH.
This is very convenient : We are cleared at the efficient immigration Check point in Mexico airport during the stop and when we arrive in Zih, it takes only a few minutes to get the luggages and out.
